various variations in humans, in rats, in China, in the USA, India, the Philippines ...
In fact, there is nothing to object to the author. It remains only the inertia of consciousness, laziness and the force of habit, which makes it necessary to leaf through the book, invent excuses and find alleged contradictions.
For example, Eugene in the recall writes "And on p. 67 an example is given, which says that to get cancer of the throat, you need to eat 270,000 sandwiches with sausage." In fact, the author does not write this. Anyone can download the introductory third chapter on the publisher's website and make sure that the author just gives this example to prove the opposite: experiments with rats fed with sodium nitrite in portions equivalent to human 270,000 sandwiches with sausage have allowed scientists (not the author !) to draw a conclusion that sodium nitrite is toxic and causes cancer in people. Further, the author gives another experiment where two groups of rats were given real human 5% and 20% milk protein per day.
